KillDeath

Killdeath, in gaming parlance, refers to the kill-death ratio (K/D), a statistic used to summarize a player's performance in multiplayer games. The K/D is computed by dividing the total number of kills a player has achieved by the total number of times they have died. A higher ratio is generally interpreted as indicating greater efficiency or effectiveness in combat, while a lower ratio suggests more frequent deaths relative to kills. The term is especially common in first-person shooters and competitive multiplayer titles.

Calculation and interpretation: K/D = kills divided by deaths. If a player has zero deaths, some games report an infinite ratio or use a predefined convention. Some titles display decimals to two or three places; others report only whole numbers or provide tiered ranges. K/D does not account for assists, objectives, or team outcomes.

Usage and limitations: K/D is widely used as a simple, comparable metric across matches, seasons, or ladders. It is most informative in games with respawns and simultaneous scoring systems, where kills contribute to score but objectives also matter. Critics argue that K/D can incentivize reckless play or ignore objective-focused behavior, and it can be misinterpreted in small sample sizes. In practice, players and analysts often supplement K/D with related metrics such as kill-death-assist ratio (KDA), average score per minute, or objective participation.

Related metrics include KDA, score per minute, and objective participation, which provide a fuller picture of player impact beyond raw kills and deaths.
